.IMPROVEMENT IN APPARATUS FORBURN-ING LIQUID FUEL AND GENERATING STEAM.

Specification forming part of Letters Patent No. llillhil, dated Juno 24,1873; application tiled April 26, 1573.

To all' whom t 'may concern y Be it known that I, TILLIAM T. SCHEIDE,

Burning Liquid Fuel and Generating Steam,

p of which the followingis a specication:

It is a well-understood fact that but a small portion of the heat -generated iu ordinary boiler-furnaces is utilized. The heat absorbed and radiated by the furnace and carried off in the form of smokel and unconsumed-carbon 'in other forms, is never less than 'three-fourths of the whole amount generated, and the average is very much more than that. 'i My invention is an vimprovement in appa'-A .ratus adapted for passing the products of combustion through the water to be converted into steam, whereby all of the heat is utilized. The invention aims at simplicity and economy of construction, with great efficiency in practical operation. y

VIn the drawing, .Figure 1 is a Vertical sec- Ation of my apparatus taken on the line x .r of' Fig 2. Fig. Z is a top-end view.

'Similar letters of reference indicate corresponding parts. A isa cylinder of suitable size and strength, having in its center a combustion-tube, B.

This tube is open at the bottom, as seen in the.' drawing, and'` is partially -filled with broken fire-brick, o r other incombustible material.- The annular spacej/iflledwith water'. Iuthe combustion tube or chamber B I use liquid fuel, or any fuel that burns withoutleaving a solidash. The' fuel is introduced through the tube `D by means of a force-pump. It may he combined with the requisite' amount of atmospheric air (or oxygen) to produce perfect combustiou'before it is pumped in, but in the apparatusshown the air is forced in through the tube E, which surrounds the fuel-tube D, leaving an annular space, F, around the fuel-tube, as seen in the drawing. The airpump is attached at the point G. The fuel and air are forced into the tire-chamber B together, and ignited by means of electricity, or by any other known means. The current or currents produced are suicient to force the entire products of combustion up from the bottom of the combustion-tube and v. through the water, thereby generating stream.-

The steam so generated is discharged from'l the .boiler into a tube attached at the point H, and conducted to another vessel, or to any desired point.

Instead of pumping the'fuel into the coinbustion-tube it may be drawn in by atmospheric pressure, the necessary vacuum being produced by the current of air forced through the outer tube E. By this apparatus the entire heat generated is utilized. The incombustible material placed in the combustioutube tends to break lthe flame and protect the tube from the effects of heat. j

Having thus described my invention, I

claim as' new and desire'to secure by Letters Patent- 'llie .improved apparatus herein described, formed of the cylinder A, provided with a perforated header cover, the centralpendent and fuel-tube D, arranged to leave an annular space between them and concentric with the tube B, all combined as .shown and described.
